I am getting actual letters in the mail from more than one banking or govt institution saying that my email address on file is being returned to them undelivered. Or, when i log onto several of my banking websites, they keep making me verify my email address. of course ebay, paypal, amazon all use this same email, and i get email from those, so its clearly not a problem with the account itself but a problem with the SMTP conversation between the sending server and my own EFA.

I'm considering removing these anyway since the postfix community advises against modifying the protocols and cipherlists except in very specialized cases (such as mandatory encryption between two parties).

I am having this same problem that started just in the last couple of months with emails from ringcentral.com. But only the notification emails not the marketing stuff. Here are some logs after enabling debugging for ringcentral.com. I tried disabling the entries in main.cf as described with no change. Any other ideas?
